Amazon - Snapshots or full data?
Hi All, I recently turned on Amazon Cloud on my RN104 running 6.6.1. So far everything seems to be working corrently, though I aside from a cursory glance at the folder structure on Amazon I have no ...
Anyone?
Hi Redwolf,
I would suggest that you do both.
You could also post on our Idea Exchange for ReadyNAS.

If files are deleted from Amazon, they should be deleted from the NAS too
The ideal way to setup would be to snapshot daily the ACD share and then if data deleted, you have a restore point within 24 hours. After some time some automatic snapshots are deleted automatically. See http://kb.netgear.com/24478/ReadyNAS-OS-6-Smart-Snapshot-Management (note if your volume was created on 6.5.0 the threshold is at 90% volume usage not 95%. You can change the threshold using the web admin GUI)
You could also consider doing local backups in addition to backups to Amazon. Getting e.g. a USB disk to backup 700GB of data would be pretty cheap. Or you could get a second NAS.
Local backups have the advantage of faster restore times, Amazon has the advantage that someone else is managing the backup device's hardware and that it's useful for disaster recovery (e.g. if a fire burnt down the building your NAS and local backup are in).
Ultimately what you decide to do depends on your budget and your risk appetite.Best practice is to have multiple backups with at least one of these offsite at all times.
Thank you for your reply. Though I am still fuzzy on snapshots. Such as, is it a real replica of my data? can I restore from it? and how big is it (relative to the size of the source data)?
The size question is important becuase I am currently syncing about 800GB to Amazon. I am still in process of the initial sync, and I project that the entire transfer time will be about about 6 days (around 150 hours), with the speed limitation being what amazon can take in from me, I have plenty of bandwidth to spare and it's currently moving at about 10Mbps. If the snapshot is indeed as large as the source data, then the snapshot will take just as long, and as my data size grows I could arrive at a point that I am perpetually uploading which I do not want to do.
So it all comes down to actually what is a snapshot?
Your points about mutiple backups are all valid. My current backup workflow is that all data reside on a resilient multidisk NAS in RAIDx, and the important shares are sync'd in near real-time to the cloud. I also maintain physical backup drive that I back up to quarterly and store in my neighbors house for additional offsite protection. in a worst case data failure, I would only be missing 3 months of data at most. I should also mention that this data is only family documents, photos and home video.

What matters more is how the snapshot looks to the amazon sync app. If you have "allow snapshot access" checked for the share, then I suggest unchecking it.
This explanation might help with your question though: https://community.netgear.com/t5/ReadyNAS-in-Business/ReadyNAS-312-Need-Help-Understanding-Snapshots/m-p/936586/highlight/true#M3041
